In mobile communication, mobile services [MSs] (e.g., phone calls, short/multimedia messages, and Internet data) incur a cost to both mobile users (MUs) and mobile service providers (MSPs). The proposed model MobPrice consists of dynamic data pricing schemes for mobile communication in order to achieve optimal usage of MSs at minimal prices. MobPrice inspires MUs to subscribe MSs with flexibility of data sharing and intra-peer exchanges, thereby reducing overall cost. The main contributions of MobPrice are three-fold. First, it proposes a novel k-level data-pricing (kDP) scheme for MSs. Second, it extends the kDP scheme with the notion of service-sharing-based pricing schemes to a collaborative peer-to-peer data-pricing (pDP) scheme and a cluster-based data-pricing (cDP) scheme to incorporate the notion of 'cluster' (made up of two or more MUs) in mobile communication. Third, our performance study shows that the proposed schemes are indeed effective in maximizing MS subscriptions and minimizing MS's price/user.

Stock price is characterized as being mutable, non-linear and stochastic. These key characteristics are known to have a direct influence on the stock markets globally. Given that the stock price data often contain both linear and non-linear patterns, no single model can be adequate in modelling and predicting time series data. The autoregressive integrated moving average (ARIMA) model cannot deal with non-linear relationships, however, it provides an accurate and effective way to process autocorrelation and non-stationary data in time series forecasting. On the other hand, the neural network provides an effective prediction of non-linear sequences. As a result, in this study, we used a hybrid ARIMA and neural network model to forecast the monthly closing price of the Shanghai composite index and Shenzhen component index.

As imported fashion products are increasing in the marketplace, country of origin information becomes a powerful product cue that can be used to gain competitive advantages of fashion brands. This study assessed the impact of multiple country of o.igin information(origin of brand and origin of production) on attitude toward the brand and product evaluation. Especially, the influence product price level was also examined. Jean was used as product stimuli and students were respondents for the empirical study. Results of this study affirmed the importance of country of brand origin and price information in brand attitude formation and product evaluation. Country of brand origin information and interaction effects of brand origin-price were significant for brand attitude formation. Country of brand origin and price information had significant influence on evaluation of Jean products.

본 연구는 유무선망간 상호접속모형을 다루고 있다. 특히, 발신자 입장에서 착신망 혹은 요금에 대한 무지가 존재하는 경우 상호접속료와 발신요금이 어떻게 책정되는 것인가를 분석하고 있다. 소비자 무지가 존재하는 경우 없을 경우 보다 착신접속료는 더욱더 높으며, 따라서 발신요금도 높아진다. 본 연구에서는 발신요금 상승을 억제 할 수 있는 여러가지 규제적 대안을 비교분석 하고 발신요금과 유무선착신접속료를 동시에 규제할 수 있는 최적 규제방안을 제안한다.

In this paper, we study a dynamic price-based call admission control algorithm for communication networks. When a call arrives at the network, the network calculates the price for the call such that its expected revenue is maximized. The optimal price is dynamically adjusted based on some information of the call, and the congestion level of the network. If the call accept the price, it is admitted. Otherwise, it is rejected. Simulation results show that our dynamic pricing algorithm provides higher call admission ratio and lower price than the static algorithm [1][2], even though they provide almost the same revenue.

Purpose The purpose of this study is to examine the potential asymmetry in price competition between the geographically defined submarkets of the lodging industry, namely the traditional and alternative accommodation facilities. Design/methodology/approach The study utilizes a spatial econometric model to empirically test for the hypothesized asymmetry in price competition. Property-level panel data on hotels and alternative accommodation facilities collected from a major online travel agency (OTA: Agoda.com) was used for this purpose. Findings Result of the analysis shows significant intra-segment spatial price competition among the properties, that is, within hotels and within alternative accommodation submarkets, respectively. However, the inter-segment competition was found to be asymmetric as hypothesized. Room rates of hotels are influenced by prices of geographically close alternative accommodations, but the reverse does not hold. Implications for practitioners and suggestions for future research are discussed along with the findings of the study.

There are a lot of shopping malls in Internet and most of consumers want to buy good goods in cheap price through the shopping malls. To support them, many sites for price comparison are constructed. But man or woman search many shopping malls and insert their price informations into database that the price comparison sites own. To overcome this disadvantage, virtual shopping malls are builded. These virtual shopping malls are connected and cooperated a lot of affiliated existing shopping malls for the cheapest price information. But, these virtual shopping mall are connected to those existing shopping malls in synchronous. So If they are connected to many existing shopping malls, we have to wait long time because of searching for many existing shopping malls. In this paper, we designed and implemented a virtual shopping mall that connect to many existing shopping malls in asynchronous. For a asynchronous communication between this virtual shopping mall and many existing shopping malls, we used JMS (Java Message Service) that is a standard Java API for MOM (Message-Oriented Middleware).

We try to study the plan to deliver the message of the hope and common peoples are diligent and we can buy the real estate in work if we make efforts hard that relieve an real estate price and analyze a timex situation. If prepared the countermeasure in the government with many real estate policy with due to a short though countermeasure which is seen at one's face. The error to the people of the policy which does not do the staring gaze to tie. This paper to pursue the stability of an real estate price and analyze the price according to an real estate policy and lead an real estate policy for a residing stability of the common people. There are we even though we grope the method to actualize and protect a lease security according to a house lease law of protection.

The information about transactions of real estate has tended to be not open. Therefore, it has been difficult for individuals to judge the proper price of each real estate. In the course of time several studies have been conducted on proposing criterions for judging the proper price of real estates. As to office buildings and apartments, it is proved techniques required for making criterions have been achieved to a certain extent. Therefore, this research aims to make methods that propose to consumers reliable criteria for judging the proper price of detached houses. The methods are based on hedonic price method and micro-level spatial elements peculiar to detached houses are considered.

This paper examines strategic competition model between offline and online retailers and draws strategic implications. Research on the price competition between conventional offline retailers and online retailers has been done through empirical approaches, however, the results are conflicting. This paper reconciles the existing conflicting empirical findings on price levels between offline and online retailers through theoretical approach. This paper analyzes how the internet market has effect on equilibrium prices of both offline and online retailers and discusses the possible reasons why there exist price differences between offline and online retailers in business to consumer electronic commerce.
